Patented Oct. 8, 1929 UNITED STATES PATENT OFFICE \VILLIAM O. THOMPSON,OF PITTSBURGH, PENNSYLVANIA, ASSIGNOR T STANDARD SANITARY IVIFG. (30., ACORPORATION OF PENNSYLVANIA FLUSTLIPIPE HOUSING Application filed August4, 1927. Serial No. 210,678.

This invention relates to plumbing fixtures and more particularly totlush pipe housings and means for securing the same in place.

Since porcelain bowls and porcelain tanks have come into use, it hasbeen customary to cover the flush pipe which extends between the tankand bowl with a porcelain housing in order to improve the appearance ofthe combined apparatus.

These housings heretofore have been more or less loosely held inposition and have been unsatisfactory on this account.

An object of this invention is to provide an improved porcelain housingfor covering the flush pipe between the bowl'and tank of a combinedfixture and also to provide means for detachably but rigidly securingthe housing in position.

This, as well as other objects which will readily appear to thoseskilled in this par ticular art, I attain by means of the housing andits attaching means described in the specification and illustrated inthe accompanying drawings.

In the drawings, Figure 1 is a side view partially in elevation andpartially in section of a fixture embodying this invention in placebetween a bowl and tank of a combined fixture. Figure 2 is a back viewin elevation of the porcelain housing forming part of the invention.Fig. 3 is a top plan view of the device for detachably but rigidlysecuring the housing to the flush pipe and in place between the bowl andtank. Fig.4 is a view taken on line 4% of Fig. 3 and Figs. 5 and 6 aredetail views of a part of the attaching device and are taken 90 one fromthe other.

In the drawings, I have illustrated in a more or less general way aporcelain tank 7, a porcelain bowl 8, and a straight flush pipe 9connecting the bowl and tank and secured in place by standard bowlfixtures 10 and stand ard tank fixtures 11.

In carrying outthis invention, I preferably employ a porcelain housing12 adapted to neatly fit in place between the tank and bowl and to hidethe flush pipe and the tank and bowl fittings 10 and 11. The back of theI upper portion of the housing is, so to speak,

cut away as as shown in Figs. 1 and 2 and a notch is provided at thecenter of the rear portion of the housing to accommodate the clampingmeans for seeming the housing in place and to the flush pipe.

The clamping means con'iprises an annular member or ring 14 formed witha projecting stud 15 which is threaded to receive a wing nut 16. Aclamping member having a cylindrical body portion 17 and a bifurcatedinner end 18 is constructed to loosely'slide on the threaded stud 15.The bifurcated. end of the clamping member straddles ring 14 and theinner surfaces of its furcate parts are curved to conform to the surfaceof the flush pipe.

A spring member 19 pierced to receive stud 15 is positioned between theouterend of the clamping member and the wing nut. This spring member ismore or less rectangular and is bent so as to provide contact feet 20 atits opposite ends which are adapted to contact with thehousing onopposite sides of notch 13.

When the housing is in position with notch 13 directly behind the flushpipe with ring 1 1 in position on the fixture and with the cylindricalportion 17 of the clamping member lying within notch 13 of the housingthe housing may be clamped in position by tight ening the wing nut. Bytightening the wing nut the curved inner ends of the furcate parts 18are forced into engagement with the flush pipe and the front of the ringis forced rearwardly in tight contact with the front of the flush pipe.In other words the pipe is sethe wing nut is screwed home it carrieswith it the spring-19 and forces its feet 20 into firm contact with theback of the housing on opposite sides of the notch 13. In this way thehousing is rigidly attached to the flush pipe and is held in fixedposition between the tank and bowl.

In assembling the device the housing 12 and the clamping means is placedin position about the pipe. The pipe is then connected to the tank 7 andbowl 8 by the standard fixtures 10 and 11. The cutaway portion of theback part of the housing 12 is rotated to the front giving access to theconnection 11 and after the connection 11 has been made, the housing isrotated about the pipe 11 to position the cutaway portion in the rear ofthe fixture to prevent its observation. The clamping means is thenoperated to render the housing in rigid fixed relation with the flushpipe as stated above.

Accordingly I have provided a sanitary fixture comprising a tank and abowl, a fiush pipe connection therebetween, a housing for the flush pipeand means for rigidly fastening the housing to the pipe and maintainingthe housing in a predetermined spaced relation to the pipe.

While I have illustrated and described but one embodiment of thisinvention it will be apparent to those skilled in the art that certainchanges, modifications, substitutions, additions and omissions may bemade in the housing and its attaching means withoutdeparting from thespirit and scope of the appended claims.

YVhat I claim as new and desire to secure by Letters Patent is:

1. A sanitary fixture comprisng a fiush pipe, a housing therefor andmeans for rigidly fastening the said housing in fixed relation to thepipe, the said means comprising an eneirclingmember, a grooved memberfitting against the pipe cooperating with the encircling member andlocking said member to the housing.

2. In a sanitary fixture and in combination with a flush pipe, a housingfor the pipe and means for holding the housing in position with relationto said pipe, said means comprising a cylindrical portion for encirclingthe pipe, an adjustable clamp secured to said cylindrical portion, aspring fitting the outer surface of the housing and cooperating with theclamping device.

3. isanit-ary fixture comprising a flush pipe, a housing for said pipe,a spring member engaging said housing and a clamping device adapted tocooperate with the spring member for maintaining the housing in rigidfixed relation to the pipe; said clamping device being independent ofthe housing, and having a member encircling said pipe.

4. in a sanitary fixture, the combination with a flush pipe, of ahousing for the pipe having an opening therein for giving access to thepipe provided with means adapted to receive a locking device, a springengaging the, outer surface of the housing, a clamping device forlocking said spring to the housing and rigidly securing the housing infixed relation to the pipe. 7

5. A sanitary fixture comprising a flush pipe, a housing therefor andmeans for rigidly fixing the housing to the pipe, the said meanscomprising a cylindrical member having a threaded stud thereon, acooperating member having a cylindrical opening and a groove therein forengaging and cooperating with the stud and cylindrical member, a springwasher and a clamping member for the stud.

6. A sanitary fixture comprising a flush pipe, a housing therefor andmeans for fastening the housing to the said pipe, the said meanscomprising a continuous annular member for engaging the outer surface ofthe pipe having a threaded stud disposed thereon, a connecting memberhaving a cylindrical opening therethrough and a slot for receiving thethreaded stud and annular member respec' tively, a spring washer for thestud having projections for engaging the housing and a clamping nut forthe threaded stud for actuating the connecting member and spring Washer.

7. A sanitary fixture comprising a flush pipe, a housin therefor, meansfor positively maintaining the housing in spaced relation to the pipe,the said means comprising a eylindrical member for engaging the pipehaving a threaded stud thereon, a cooperating member for the stud andthe cylindrical member adapted to lie within the housing and a clampingmember for the stud.

In testimony whereof, I have hereunto subscribed my name this 22nd dayof July, 1927.
